I found out that the BP on my corner sells ethenol-free premium gas. The label says it only to be used in collector cars and off road toys. Is that stuff any good or is it just a ploy to get an extra 5 cents a gallon?
my car LOVES it, in fact i just ran a tank of s/a 100 through, it ran BETTER on the BP 92 non oxy ive been running. i get it as much as possible, i dont dislike ethanol, but i cant argue with how great it runs
When I head home to the parents i always fill it up as often as possible with 93 non-oxy. the rex loves it.
Been running BP 92 nonoxy in my 9-2x Aero since I bought it last year. Only 2 gas stations in the town where I live, and only the BP sells premium. So I really don't have a choice (that will be my excuse if anyone complains ). My car loves it as well, I commute 60 miles a day and average 27-28 mpg all summer long. Drops a bit in the winter, but not too much.
The last tank I put in was 92 non-oxy. I don't recall it ever being 93, unless 93 is at selected gas stations because all the non-oxy I've seen are 92 oct.
93 non-oxy I found it in Eastern WI. parents live half way between Milwaukee and Green Bay, in Plymouth.
I run 91 non oxy. Never seen anything higher around the ep area. With the non oxy your car will run a little quicker and it will also get better gas milage.
Yup, better gas mileage will be achieved with straight gas. Ethanol blended gasoline requires more fuel by volume to be injected to achieve a stoich burn. The other benefit of running non-oxy is that it will free up a bit of injector duty cycle headroom for the tiny injectors in the 2.0L WRX.
Shannon, I think one of the Bobby and Steve's gas station sells it. Not sure though. Maybe we should start a sticky with gas stations that sell it. I know of three. -Sinclair Station, Hyw 5 and 101, Channhassen. Does not advertise that its non oxy but I have talked to the guy and he told me thats what the premum is. -Mobil, Valley View Rd and 494, Eden Prairie -Mobil, Eden Prairie Rd and Excelcior Blvd. Mtka. (Have to pay extra for it)
The Minn Street Rod Assoc has a list of statewide non-oxy fuel stations at their web site. I think it is msra.com. Non oxy is great in my Harley and my 911.
Ethanol is great for octane, poor for power. It much less BTUs then straight gas. Here's the latest list: http://www.msra.com/NonOxygenatedFuel/NonOxygenated Fuel List 06.01.06.pdf And Sunco GT100: http://www.sunocoinc.com/Site/Consumer/RaceFuels/260GT100Locations/Minnesota.htm
You use more ethanol though, so the less BTUs ends up evening out. Also ethanol drops your air charge temps, which is usually good on turbo cars. In the Evo, DSM and Turbo Honda worlds, people actually try to run more ethanol. Some people will run a couple gallons of E85 mixed in with their normal 10% ethanol 92 octane, to allow more boost daily. Running straight E85 is like race gas everyday. The gas mileage isn't as good, but it's a cheap fuel for high power. Methanol has even less BTUs than normal gas, but like ethanol, you need to use a lot more of it. You need even more of it than ethanol, which ends actually getting around a 15% BTU gain over all, which is why methanol is more popular than ethanol in drag racing, because you get roughly a 15% gain in HP by running methanol versus methanol or race gas.
Agreed x eleventy. While there is less btu/volume in ethanol blended fuel, you need to run a higher volume of fuel to hit stoich anyways. So like our kind friends at DB stated, it ends up being a wash in the long run, but with lower egts. I'm going to start running straight e85 this spring once they switch back to their summer blend -- and hopefully open up a station closer to my house, hehehe.
Yea, the E85 mixture change 4 times a year here is kind of a pain for cars that would want to run it year round. The main thing that holds a lot of people back from running E85 is the much higher fuel pump/injector/fuel line demands.
The Non-Oxy fuel lst from MSRA http://www.msra.com/NonOxygenatedFuel/NonOxygenated%20Fuel%20List%2006.01.06.pdf
Non-Oxy FTW. The station in Downtown Prior Lake sells it too. I gave the clerk at the counter a long lesson in BTUs and all that jazz to make him quit saying "That's an awfully new collector car." After I explain to him that it has more "power" in it than oxygenated/blended gas, he immediately says "Wow. I'm gonna have to start running that in my civic!!!" /sobsob
It's at the BP on the corner of Dale St. and County Rd B I think. Just head south on Dale 1 block from Hwy 36 in Roseville.
The BP I stoped at yesturday on my way home from mad-town was non oxy 93. I usually go to the only gas station in town that still has no ethenol I feel like the car runs better.
Here is some info on the blending: "The ethanol and gasoline levels used in producing E85 will vary by season and from region to region. Minnesota, because of its location in the northern United States, may have an ethanol content of 70 vol% in April, while Texas may have a (minimum) content of 79 vol% during the same month. The E85 blends in Minnesota will vary from a minimum of 70 vol% in winter to a minimum 79 vol% ethanol in summer. The following blending ratios (Table 1) should be used for ethanol blending in the northern tier of the United States. Season Months Blend (minimum ethanol content) Spring March, April, May 74 vol% Summer June, July, August 79 vol% Fall September, October, November 74 vol% Winter December, January, February 70 vol% "
I tuned an Evo 9 last summer with a couple bolt-ons twice. The first time he came in, he was running some 92 non-oxy and it knocked much easier than other Evo 9s that I had tuned at the same boost level with the same mods. It made 273awhp/259 tq. We were expecting more like 285-290awhp and I told him that his car knocked too easy for the setup. He came back about a month later running normal BP 92 with the 10% ethanol in it and an additional 2 gallons of E85 mixed in. We were able to make 300awhp/278tq on the second tune.
Ummmm....you missed the part where more ethanol-blended fuel (by volume) is used in the engine thus making the whole argument a wash.
